PU Silicone Stabilisers



The Tegostab® portfolio from EVONIK contains surfactants for polyurethane (PUR) and polyisocyanurate (PIR) systems. It includes silicone based surfactants for use in all kinds of PUR and PIR foams. Additionally organic surface active products designed for special applications are offered.

Silicone surfactants promote the emulsification of the A-component, regulate the nucleation/cell formation and stabilise the cells in the final foam.

The silicone free surfactants were developed for micro-cellular systems and rigid foam applications providing an excellent adhesion and a smooth surface.

Choosing the right surfactant significantly affects the physical and mechanical properties of the foam. This includes emission reduction, insulating property improvements (lambda values), achievement of the desired cell structure as well as an increased flame resistance.

The Tegostab® grades are used in soft block, moulded and spray foams as well as insulation panels and microcellular foams such as shoe soles. In non-cellular applications, the surfactants are used in the field of adhesives, sealants, elastomers casting resins and release agents.
